"Gen. Petraeus has simply erred in linking the challenges faced by the US and coalition forces in the region to a solution of the Israeli-Arab conflict, and blaming extremist activities on the absence of peace and the perceived US favoritism for Israel. This linkage is dangerous and counterproductive."

This may have contributed to his leaving. Challenging Israeli Lobby power is high-risk. Perhaps it decided Petraeus had to go.

Whether so or not, he's a four-star, now defrocked, failure. Another paper emperor has no clothes. He never did but now we know.

"Forget what you've heard - could this be why Petraeus resigned?" Speculation "focus(ed) in large part on his role in an alleged cover-up of the attacks against the U.S. mission in Benghazi this past September."

Overlooked are secret CIA Benghazi operations. Involved are heavy weapons sent to Syrian opposition fighters. Petraeus left days before his scheduled congressional testimony.

He'll either come voluntarily or be subpoenaed. What he'll be asked or say remains to be seen. If it's too controversial, expect closed hearings.

The Benghazi operation is erroneously called a US consulate. It's "a meeting place to coordinate aid for the rebel-led insurgencies in the Middle East."

Tasks performed include "collaborating with Arab countries on the recruitment of fighters -- including jihadists -- to target Bashar al-Assad's regime in Syria."
